Only temporarily. When I force myself to do something differently, the novelty might pull the weight off for a bit. It always comes back though. Exercise helps a little, when I can force myself to do it (which is hard; habits are slow to be gained, but can be broken quickly). What makes the most difference, is fasting (generally day fasts) and forcibly resetting my sleep schedule when it becomes nocturnal. The feeling of hunger is something real that I can hold on to, something to feel, even if it doesn't feel good. Waking early in the morning and sleeping at night seems to be helpful, but less so now that daylight only covers about 8 hours that I'm usually not outside for.
